Efficacy and safety of irinotecan/platinum versus etoposide/platinum chemotherapy for extensive-stage small cell lung cancer
To compare the efficacy and safety of etoposide plus platinum (EP) and irinotecan plus platinum (IP) regimens for treatment of extensive-stage small cell lung cancer (SCLC).
Methods
2
This retrospective study was conducted among 144 patients with extensive-stage SCLC receiving chemotherapy with EP regimen (65 cases) or IP regimen (79 cases) in our hospital during the period from 2013 to 2017. Twenty-two patients in EP group and 30 in IP group also received adjuvant radiotherapy. We compared the Objective response rate (ORR) and safety of these 2 regimens
and analyzed the effects of radiotherapy and lymphocyte subset distribution on the survival outcomes of the patients.
Results
2
No significant difference was found between EP and IP groups in the ORR
disease control rate
median progression-free survival time
or medial overall survival time (mOS; 13.95
vs
14.10 months
P
=0.120). In both groups
the combination of chest radiotherapy significantly improved the mPFS and mOS of the patients as compared with chemotherapy alone. The patients with lowered counts of T4 and T8 lymphocyte subpopulations had significantly shorter mPFS and mOS than those with normal T4 and T8 cell counts. Compared with IP regimen
EP regimen was associated with a significantly lower incidence of diarrhea (7.7%
vs
46.8%
P
=0.020) but higher incidences of neutropenia (52.3%
vs
22.8%
P
=0.001) and anemia (73.8%
vs
40.5%
P
=0.013).
Conclusion
2
The therapeutic efficacy of EP and IP regimens is comparable for treatment of extensive-stage SCLC
and adjuvant radiotherapy can significantly improve the clinical outcomes of the patients. The patients with reduced counts of T4 and T8 lymphocyte subsets have poorer outcomes than those with normal counts. EP regimen is associated with high incidences of neutropenia and anemia
and IP regimen with a high incidence of diarrhea in the patients.
